anus_24a_n.jpg: Upright abdomen x-ray in an infant with abdominal emergency. Visible are intestinal loops. They are overdistended with air and in the right upper quadrant an air-fluid level may be suggested.
Abdominal x-ray in two planes belongs not usually to the additional examinations in suspected intussusception because the distribution of air may be unspecific and
air-fluid levels are observed only in the late stage of obstructive ileus. In abdomen
x-ray the suspicion of intussusception arises if the abdomen is void of air and/or in case of amputation or filling of the ascending colon by the invagination. The presented findings are not typical for an early but for an intermediate stage of invagination.
